Given numbers are 413, 720, 639, 856

The list of prime factors of all numbers are

Prime factors of 413 are 7 x 59

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 639 are 3 x 3 x 71

Prime factors of 856 are 2 x 2 x 2 x 107

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 413, 720, 639, 856

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(413, 720) = 297360

GCD(413, 720) = ( 413 x 720 ) / 297360

= 413 / 720

= 413

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

So, Greatest Common Divisor of 413, 720, 639, 856 is 1
